SCALE.

Application filed December 19, 1912. Serial No. 737,596.

To all whom it may concern: 1

Be it known that}, HARRY S.Bnusn1v, a citizen of the United States, residing at Toledo, county of Lucas, and State of Ohio, have invented certain new and useful Improvements in Scales, of which the following is a specification.

My invention relates more particularly to counterscales of the type commonly employed in drug stores and consistsin certain features of construction by which the sen sitiveness and accuracy of the scale is increased and other advantages obtained which will be apparent from a reading of the following detailed description in connection with the accompanying drawing forming a part of the application. It is to be understood, however, that the detailed disclosure though of the preferred form of my invention is given for the purpose of illustration only, my invention being broader than the specific construction set forth.

In the claims below i have endeavored to point; out my invention in such terms as to distinguish it'from the prior art but it is to be understood that in presenting them it is not my intention to abandon or relinquish any part of the invention.

The accompanying drawing is a front elevation ofmy invention as embodied in its preferred form in a scale adapted for counter use.

The base of the scale is shown as of substantially the usual type haij'inga bottom plate of metal or other suitable material provided at its corners with adjustable feet 2, 2, and the rectangular casing 3 mounted thereon comprises suitable end pieces or frames 4, l and panels 5, 5 of plate glass, a top 6 resting upon the end walls and panels completingthe box-like casing or inclosure.

Over the central portion of the casingis supported a housing 7 communicating with the former containing a weight offsetting means and comprising a fan-shaped chart casing 8. At opposite ends of the box-like casing 3 are fulcrumed two similar levers 9, 9 of the second order which are slightly crooked or elbowed as at 10, 10 and connected at their inner ends by straps 11, 11 with the segments 12, 12 mounted to turn with a casting 18 to which is secured a load offsetting pendulum 14-. The casting 13 is transversely bored and mounted upon a cylindrical arbor 13 uponwhich are also mountk ed in like manner the segments referred to above, whose angular position with -refer-. ence to the casting is adjusted by screws 13,- ll" tapped through flanges 12, 12 and bearmg upon the casting above and below theeo axis thereof, as plainly appears in the draw- 1 ing. An indicator hand 16 is mounted to turn with the pendulum structure and'to i11 dicate the weight of a commodity placed upon the scale pan 21 One of the scale levers or beams, it matters not which, is prolonged beyond the point of attachment of its strap 11, and connected to the piston rod 18 of a dash .pot 19. for preventing violent movement of the parts of the scale and bringing them quickly to rest. Each of the scale levers isprovided l at the elbow or bend, above mentioned, with upwardly directed knife edges upon which are borne the down turned ends of a spider 20 connected to the scale pan 21, 21 Check rods 22 are also connected to the spiders and to check links 23 for the usual purpose of retaining the scale pans in substantially horizontal positions. In order to seal the scale each check rod or stem 22 is provided at its lower end with a shot box 24, 2a which not only serves to adjust the scale but by reason of its distance below the the counterbalancing weight commonly used specifically for this purpose. \Vhen a commodity to be weighed is placed upon the scale pan 21 the system is thrown out of balance and the pendulum 14 moves upward until its torsional effect counterbalances the weight of the commodity, which is then read upon the scale; if, however, the weight of the commodity is in excess of the capacity of the chart, movable poises or weights are added to the scale pan 21 until the weight of the commodity is counterbalanced to within the capacity of the chart. The total weight of the commodity is found by adding the weights placed upon the scale pan 21 to that indicated upon the chart;

' termediate said beams and above the same,

I claim:

1. In a Weighing machine, a pair of scale beams, scale pans mounted thereon, a pendulum weight ofl'setting means pivoted intermediate said beams, a pair of segments separately adjustable annularly with relation to saidpendulum, an indicator carried by the pendulum, and a chart with which the indicator cooperates.

in a weighing scale, a pair of scale beams, scale pans mounted thereon, a pendulum weight-offsetting means pivoted ina pair of segments angularl adjustable about the axis of the pendulum, adjusting screws for individually adjusting the same with relation to the pendulum, ribbons eonnected at their lower ends to the ends of the scale beams and passing over said segments, an indicator chart and a hand mounted upon HARRY S. BERG-EN.
